FERRU LE.

SPECIFICATION forming part of Letters Patent No. 703,457, dated July 1,1902.

Application iilecl November 8 1900. Serial No. 35,885. (No model.)

To all whom it may conccrmi Be it known. that I, CARL PERDELWITZ,merchant, a citizen of the Kingdom of Prussia, residing at Berlin,Germany, have invented certain new and useful Improvements in l Ferrulesfor Canes and Umbrellas, (for which I have received a gebrauchsmuster inGermany, No. 185,920, dated April l0, 1900,) of which the following is aclear specification.

My invention relates to a ferrule for canes and umbrellas, the objectbeing to greatly deaden the noise of canes made of metal tube or hardheavy wood when striking against the stone pavement. A further advantageof my invention is thatthedisagreeable shock felt in the wrist whenstriking against hard soil is completely neutralized by the ferrule. Thebolt arrangedinside the ferrule is exchangeable.

The advantages mentioned above permit of constructing canes andumbrellas of one single metal tube. Hitherto there was little desire forcanes of this kind on account of the disagreeable noise caused by themetal cane when striking against hard soil.

Referring to the drawings, Figure 1 shows a vertical section of a canemade of drawn metal tube. Fig. 2 shows a vertical section of theferrule. Fig. 3 shows a horizontal section. of the ferrule. Fig. 4:shows a section of the ferrule as applied to common wooden canes. v

At the lower end, Fig. 2, of the metal-tube cane at a there is astricture, against which presses a plate b, consisting of wood or metal.e represents an elastic stopper of india-rubber or leather; c, the bolt,consisting of hard or highlyresistant met-al. lThe bolt inside the tubeis inclosed in a casing or ring )@,made of india-rubber,being thusfirmly pressed into the said tube', so thatit cannot fall out. Into thelower end of the cane the metal ring g is inserted, which serves as areinforcementpiece of the turned end of the tube.

stopper e is pressed directly against the 5o wooden stick, the case ofthe ferrule inclosing the india-rubber parts being connected with thecane by means of a pin or screw.

Since the bolt is insulated by means of an elastic covering, it can movespring-like, and thus catch the shocks in such a way as to weaken thesound and eifectually prevent the transmission of the shock to the wristof the person using the cane. The bolt, which is subject to wear, caneasily be removed and replaced by a new one.

Modifications in the shape of the single parts, inasmuch as they havethe same effect, do not affect the invention.

Having thus fullydescribed my invention, what I claim as my invention,and desire to secure by Letters Patent of the United States, 1s-

l. In combination, with a cane or umbrella madeof metal tube, a ferrule,comprising an elastic stopperA e, pressed into the said cane orumbrella, an elastic casin g or ring f, a bolt c, consisting of hardor'highly-resistant metal and a metal ringi g, substantially for thepurpose as described.

2. In combination with a cane or umbrella stick of Wood, aferrule,comprising an elastic stopper c, an elastic casing or ring f, a bolt c,consisting of hard or highly-resistant metal and a metal ring g,substantially for the purpose as described.
